Patented Feb'. 18, 1941 UNITED STATES/Q PATENT OFFICE Application October 8, 1937, Serial No. 167,886 In Germany July 22, 1937 "4 Claims. (01. 98-41) This invention relates to an improved mouth-' piece or outlet device for use with apparatus for blowing air in a concentrated or diilused current into rooms or enclosed spaces, for example ships holds, or for the ventilation of railway carriages and aircraft cabins and the like, in which 'a blast nozzle open on two sides is ar-. ranged in a spherical member rotatable in all directions, under one opening of which nozzle I a deflector is provided for producing a difiused air current.

Air outlet devices, for this kin'd'are described in British specification No. 350,244, and have'the disadvantage that owing to the fact that said deflector lies outside the area of the spherical member, the possibility ofaltering the direction of the concentrated air current is considerably limited and thus the degree of usefulness of the apparatus is essentially lessened. v

The object of this invention is toovercome these disadvantages and to this end, according to the invention, the member forming the deflector surface forms a part of the rotatable spherical member, for example the back of the deflector surface member may be formed as a calotte oi the solid or hollow spherical ,outlet The deflector, formed at the same time as a closing member for the nozzle, may be arran ed so as to be displaceable-into the interior of the sphere and thus the outlet device is rotatable v into any working position as desired.

Furthermore, as the outlet openings for the concentrated and for the 'diflused air current are entirely separated from: one another any desired direction can also be given in accordance s; invention toathe concentrated air that the invention may be fully; understood I lwill now describe one embodiment by way of example by. reference to the accom- Y panying drawing, which shows a device, constructed i1- accordance with the invention, diagrammatic ally'in section.

' Referring-to the drawing:

l indicates a blast nozzle formed cylindrical or conical, which lies' in the solid or hollow spherical. air outlet 2, which, for its part, is '.rotatably arranged as/ a snug flt in a support f formed by the cup-shaped bearings I, 4'.

The outlet openings of the nozzle are indicated at 5and6. In front of or beneath. the nozzle opening 6 is arranged a deflector member I having a flat deflecting surface, the back or rear side of. which may be curved, as shown, or of any other suitable shape. The deflector 1, being connected with the hollow outlet 2, is rotatable therewith in the support formed by the bearings 3,.4. Y 5 The deflector surface 1 is formed with a spin-. die 8 which is displaceably mounted in a socket 9. The said guide socket 9 is secured in known manner by-means of one or more arms or spokes 10 in to the inner wall of the nozzle I. The deflector surface I can be displacedtowards the centre of the spherical member 2 so as to close the nozzle opening 6, the spindle 8 being correspondingly moved into the socket 9.

In the opposite direction the degree of movement of the spindle 8 is limited by a stop" ll formed, for example, as a ball,:such that the deflector member I is constantly retained within the peripheral line of the spherical outlet memher 2; In the example shown in the drawing, the outermost position of the deflector member I is such that the rear side'thereof lies in the peripheral lineof the outlet member 2 and is shaped to coincide therewith throughout its If the apparatus is arranged, for example, in an air feed channel H and the air is fed in the direction of the arrow l2, then, with the parts in thepositibn shown; the air will pass outwardly through the nozzle opening 5, strike the deflector surface l and bent thereby in all directions, will enter into-the room as a diffused air current in the direction of the arrows l3. In this way, by means of this apparatus it is possible to .vary the. direction of the middle axis of the air current. v

By displacing the deflector member I towards the inside, of the spherical member 2 the size of the air outletopening for the diffused air current can be varied and also the nozzle opening 6 can be completely closed. [If the spherical out- '45 let device is rotated so far that the nozzle opening 5 projects out of the air channel ll intothe room, then the air enters the apparatus through the opening 6' and enters the room through the opening 5 as a'concentrated air current, the to direction of the middle axis of which can be alv I tered as desired by rotation of" the spherical member 2. Moreover, with this position of the completely shut ofl by suitable variation of the position of the deflector member I towards the be formed as a rotation body of a curve or the like corresponding to deflnite requirements as to conical dispersing forms.
